无法实例化 Windsor 自定义组件激活器

发布于 2024-09-04 23:32:08 字数 424 浏览 4 评论 0原文

我在调用 Resolve 时遇到异常：

KernelException: Could not instantiate custom activator
Inner Exception:
{"Constructor on type 'MyProj.MyAdapter`1[[MyProj.MyBusinessObject, MyAsm, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' not found."}

那里肯定有一个公共无参数构造函数（并且我已经在运行时使用反射验证了这一点）...所以我认为问题可能与它是通用的这一事实有关？我尝试获取组件模型对象并将 RequiresGenericArguments 设置为 true，但这并没有让我有任何进展。

任何帮助将不胜感激！谢谢。

I'm getting an exception calling Resolve:

KernelException: Could not instantiate custom activator
Inner Exception:
{"Constructor on type 'MyProj.MyAdapter`1[[MyProj.MyBusinessObject, MyAsm, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' not found."}

There's definitely a public parameterless constructor there (and I've verified this using reflection at runtime)...so I figure the problem might have to do with the fact that it's generic? I've tried getting the component model object and setting RequiresGenericArguments to true, but that hasn't gotten me anywhere.

Any help would be much appreciated! Thanks.

Windsor 不使用默认构造函数来实例化激活器。

新版本抛出了更有用的异常消息：

Castle.MicroKernel.KernelException : Could not instantiate custom activator
  ----> System.ArgumentException : Type Castle.Windsor.Tests.ActivatorWithoutCorrectConstructor does not have a public constructor matching arguments of the following types:
Castle.Core.ComponentModel
Castle.MicroKernel.DefaultKernel
Castle.MicroKernel.ComponentInstanceDelegate
Castle.MicroKernel.ComponentInstanceDelegate

所以你需要一个像这样的构造函数

public YourActivator(ComponentModel model, IKernel kernel,
                                    ComponentInstanceDelegate onCreation,
                                    ComponentInstanceDelegate onDestruction)

Windsor is not using default constructor to instantiate activators.

The new version throws a more helpful exception message:

Castle.MicroKernel.KernelException : Could not instantiate custom activator
  ----> System.ArgumentException : Type Castle.Windsor.Tests.ActivatorWithoutCorrectConstructor does not have a public constructor matching arguments of the following types:
Castle.Core.ComponentModel
Castle.MicroKernel.DefaultKernel
Castle.MicroKernel.ComponentInstanceDelegate
Castle.MicroKernel.ComponentInstanceDelegate

So you need a constructor like this

public YourActivator(ComponentModel model, IKernel kernel,
                                    ComponentInstanceDelegate onCreation,
                                    ComponentInstanceDelegate onDestruction)
